TerraCycle a small New Jersey-based organic plant-food company is being sued by industry giant Scotts Miracle-Gro. ❋ Unknown (2007)
Vegfam, a U. K.-based charity that funds sustainable plant-food projects, estimates that a 10-acre farm can support 60 people by growing soy, 24 people by growing wheat or 10 people by growing corn — but only two by raising cattle. ❋ Unknown (2008)
Bones thus, when applied in large quantities, may not merely act directly as suppliers of plant-food, but in the course of their putrefaction may act upon a certain amount of the inert fertilising matter of the soil and render it available. ❋ Charles Morton Aikman (N/A)
Huxtable and Thompson on retention of plant-food by soil, 57. ❋ Charles Morton Aikman (N/A)
But let that soil be water-soaked, and have the proper bacteria at work, and the material is in plant-food form. ❋ Ellen Eddy Shaw (N/A)
_Indirect_, because their value is due, not to their direct action as suppliers of plant-food -- like those manures we have hitherto been engaged in discussing -- but to their indirect action. ❋ Charles Morton Aikman (N/A)
Nitrification is also dependent on the presence of plant-food suitable for organisms of low character. ❋ Various (N/A)
But a much more important property of salt is its solvent action on the plant-food present in the soil. ❋ Charles Morton Aikman (N/A)
By treating a soil with water, we obtain a certain amount of plant-food dissolved in the water. ❋ Charles Morton Aikman (N/A)
On the other hand, a general manure prevents or diminishes the consumption of the elements of plant-food contained in the soil, and if added in sufficient abundance, may cause them to accumulate in it, and even enable an almost absolutely barren soil to yield a tolerable crop. ❋ Thomas Anderson (N/A)
Consequently it is of primary importance to examine into the conditions which regulate the absorption of this important plant-food by the soil. ❋ Charles Morton Aikman (N/A)
As a supplier of the necessary elements of plant-food 268 ❋ Charles Morton Aikman (N/A)
That substance differs in no respect from any other element of plant-food, and used in this way is to all intents and purposes a special manure, and acts merely by bringing into play those substances which the soil already contains. ❋ Thomas Anderson (N/A)
Especially is this the case with such a necessary plant-food as potash, of which there is generally present, in all likelihood, an excess. ❋ Charles Morton Aikman (N/A)
Tull in asserting that plants feed on earth; air and water alone, in his opinion, furnish the supply of plant-food. ❋ Various (N/A)
Further, the amount of this available plant-food will vary with different crops -- one crop being able to grow where another crop would starve. ❋ Charles Morton Aikman (N/A)
Grandeau, Professor, on forms of plant-food in soil, 107; on loss of phosphoric acid, 207. ❋ Charles Morton Aikman (N/A)
In soils which are either excessively tenacious or light, the accumulation of the manure close to the plants has also the effect of producing an artificial soil in their immediate neighbourhood, containing abundance of plant-food, and having physical properties better fitted for the support of the plant. ❋ Thomas Anderson (N/A)
Lastly, its influence on the micro-organic life of the soil, which plays such an important part in the preparation and elaboration of plant-food, is of the highest importance. ❋ Charles Morton Aikman (N/A)
